Im my example, I've created a sidenav with three levels of the dropdown element. Levl 1 and 2 are simply hierarchies and don't have pages. Level 3 links to individual pages:
Is there a way I can build the sidenav with levels so that when a page is selected, the hierarchies stay open. I.e., they are completely user-controlled. I tried to create this with divs and interactions, but because interactions target classes the interaction would open ALL instances of level 1 at the same time.
